The present invention relates to the field of lighting equipment, and in particular to a lighting equipment.
Traditional lighting equipment, such as a flashlight and a searchlight, usually use LED lights as the light source inside their lamp heads, can only perform simple illumination, and are prone to cause dizziness and discomfort to a person after looking at the LED light sources for a long period, or even damage the eyes.
Generally, prior lighting equipments are only provided with an LED light source, the long and short distance light adjustment of which is usually implemented by adjusting the distance between a lamp bead and a reflective surface to achieve the convergence and divergence effects of the light source. The most common way to adjust the distance between the lamp bead and an outermost lampshade is by drawing or rotating a head portion of the flashlight, thereby adjusting the convergence and divergence effects of a light beam. When these two ways are adopted to adjust the light beam of the flashlight, the user often needs to use two hands to operate, which is inconvenient. In addition, since the head portion of the flashlight is designed to be a drawable or rotatable shape, there is some gap at a joint between the head portion and an outer casing, inevitably, and the size of such gap is difficult to be controlled factitiously. In case of long-term use, the gap at the joint between the head portion of the flashlight and the outer casing gradually increases, thereby causing undesirable practical water-proof effects of the flashlight.
A handheld lighting device, which can adjust the long and short distance light effects by using a single hand, is commercially desirable in that the operation is simpler and more convenient.

The inner side wall of the reflective member inclosing plate 1014 is provided with at least one reflective member snap latch 1015, evenly distributed on the inner side wall of the reflective member inclosing plate 1014. Preferably, three reflective member snap latches 1015 are arranged on trisection points of the reflective member inclosing plate 1014. The reflective member inclosing plate 1014 is provided with at least one inclosing plate notch 1016, respectively corresponding to each reflective member through hole 1013. The reflective member snap latch 1015 and the inclosing plate notch 1016 are used for fixing the COB lamp plate 102.
In the present embodiment, the COB lamp plate 102 and the LED lamp plate 104 will dissipate heat during operation. Since the COB lamp plate 102 and the LED lamp plate 104 are adjacent or close to each other in position and will dissipate more heat when operating at the same time, the reflective member 101, as a member directly contacting the COB lamp plate 102 and the LED lamp plate 104, must have good heat dissipating effect.
Each member in the reflective member 101 is designed integrally. The reflective member is made from metal materials, with good heat dissipating performance wholly, so as to dissipate the heat generated during the operation of the COB lamp plate 102. In order to further improve the heat dissipating effect of the reflective member, the reflective member 101 can further include a heat fin 1017 and a heat sink 1018. The heat fin 1017 protrudes from the outer side wall of the tapered reflective surface 1012; the heat sink 1018 protrudes from the surface of the reflective member main plate 1011 and is connected to the heat fin 1017. The reflective member 101 can be provided with several heat dissipating holes (not shown in the drawing) and can be arranged at any position without affecting the operation of other members. The heat fin 1017, the heat sink 1018 and the heat dissipating holes can effectively increase a surface area of the whole reflective member 101 and increase the heat dissipating efficiency.
In the present embodiment, a plurality of heat dissipation channels (not shown in the drawing) is included. The heat dissipation channel is an unsealed space, can be enclosed by the heat fin 1017 and/or the heat sink 1018, or can be enclosed by the reflective member 101 and the adjacent other members. A relatively large air channel is formed around the tapered reflective surface 1012 and is communicated to the reflective member through hole 1013, such that the air in the rear space of the tapered reflective surface 1012 can be communicated to the outside air, which further enhances the heat dissipating effect.
